Shield Arms Premium Magazine Catch Features The Shield Arms Premium Magazine Catch is purpose built for left-hand shooters running a Glock 43X or Glock 48 and it is not an ambidextrous design. By committing to one hand orientation Shield Arms was able to remove hard angles from the bottom of the catch that would otherwise snag a magazine on the way in. That change translates directly into smoother more reliable reloads under pressure which matters most when the shooter needs the gun running again instantly. The catch face itself is extended about .03 inch longer than Shield Arms standard mag catch giving slightly more engagement with the magazine for a more confident positive lock. The Premium Magazine Catch comes standard in a black anodized finish for corrosion resistance and a clean duty-ready appearance with extended knurling at 1/32 inch that improves grip and makes the catch easier to actuate quickly with a gloved or sweaty hand. It is machined from steel rather than polymer built to hold up to repeated hard use without the wear a factory catch can show over time. Shield Arms notes this catch does not function with plastic OEM magazines so it is intended to be run with their steel S15 magazine for proper engagement. Backed by a lifetime warranty and made in the USA it is a durable left-hand specific upgrade for Glock 43X and 48 owners who want faster more reliable reloads.
